Over-expression of aspartyl (asparagynal)-β-hydroxylase (ASPH) contributes to hepatocellular carcinoma (HCC) invasiveness, but the role of ASPH hydroxylase activity in this process remains to be defined. As such, the current study investigated the role of ASPH hydroxylase activity in downstream signalling of HCC tumorgenesis and, specifically, metastasis development. Over-expression of wild-type ASPH, but not a hydroxylase mutant, promoted HCC cell migration in vitro, as well as intrahepatic and distant metastases in vivo...

KiSS-1 was first described as a metastasis suppressor gene in malignant melanoma. KiSS-1 encodes a 145 amino-acid residue peptide that is further processed, producing the 54 amino acid metastin and shorter peptides collectively named kisspeptins (KPs). KPs bind and activate KiSS-1R (GPR54). Although the KPs system has been extensively studied for its role in endocrinology of reproductive axis in mammals, its role in cancer is still controversial. Experimental evidences show that KP system exerts an anti-metastatic effect by the regulation of cellular migration and invasion in several cancer types...

Nowadays, risk factors of triple-negative breast cancer (TNBC) metastasis are not well identified. Our present study reveals that an industrial chemical, bisphenol S (BPS), can promote the migration, but not the proliferation, of TNBC cells in vitro. BPS activates YAP, a key effector of Hippo pathway, by inhibiting its phosphorylation, which promotes YAP nuclear accumulation and up-regulates its downstream genes such as CTGF and ANKRD1. Inhibition of YAP blocks the BPS-triggered cell migration and up-regulation of fibronectin (FN) and vimentin (Vim)...

Our previous work has demonstrated that extracellular ATP is an important pro-invasive factor, and in this study, we tapped into a possible mechanism involved. We discovered that ATP could upregulate both the intracellular expression and secretion of S100A4 in breast cancer cells and fibroblasts. Apart from stimulating breast cancer cell motility via intracellular S100A4, ATP enhanced the ability of breast cancer cells to transform fibroblasts into cancer-associated fibroblast (CAF)-like cells, which in turn secreted S100A4 to further promote cancer cell motility...

β3GnT8, a key polylactosamine synthase, plays a vital role in progression of various types of human cancer. The role of β3GnT8 in hepatocellular carcinoma (HCC) and the underlying mechanisms, however, remain largely unknown. In this study, we found that β3GnT8 and polylactosamine were highly expressed in HCC tissues compared with those in adjacent paracancer tissues. Overexpression of β3GnT8 promoted while knockdown of β3GnT8 inhibited HCC cell invasion and migration in vitro . Importantly, enhanced tumorigenesis was observed in nude mice inoculated with β3GnT8-overexpressing HCC cells, suggesting that β3GnT8 is important for HCC development in vitro and in vivo ...

The chronic inflammatory microenvironment within or surrounding the primary renal cell carcinoma (RCC) site promotes oncogenic transformation as well as contributes to the development of metastasis. G3BP stress granule assembly factor 1 (G3BP1) was found to be involved in the regulation of multiple cellular functions. However, its functions in RCC have not been previously explored. Here, we first showed that the expression of G3BP1 is elevated in human RCC and correlates with RCC progression. In cultured RCC cells, knockdown of G3BP1 results in inhibition of tumor cell proliferation, migration, and invasion, consistently with the alteration of epithelial-mesenchymal transition (EMT) and cell proliferative markers, including Cadherins, Vimentin, Snail, Slug, c-Myc, and cyclin D1...

The mechanism by which gastrin promotes pancreatic cancer cell metastasis is unclear. The process of directing polarized cancer cells toward the extracellular matrix is principally required for invasion and distant metastasis; however, whether gastrin can induce this process and its underlying mechanism remain to be elucidated. In this study, we found that gastrin-induced phosphorylation of paxillin at tyrosine 31/118 and RhoA activation as well as promoted the metastasis of PANC-1 cancer cells. Depletion of Gα12 and Gα13 inhibited the phosphorylation of paxillin and downstream activation of GTP-RhoA, blocked the formation and aggregation of focal adhesions and facilitated polarization of actin filaments induced by gastrin...

The human ortholog of the Drosophila ecdysoneless gene (ECD) is required for embryonic development and cell-cycle progression; however, its role in cancer progression and metastasis remains unclear. Here, we found that ECD is frequently overexpressed in gastric cancer (GC), especially in metastatic GC, and is correlated with poor clinical outcomes in GC patients. Silencing ECD inhibited GC migration and invasion in vitro and metastasis in vivo, while ECD overexpression promoted GC migration and invasion. ECD promoted GC invasion and metastasis by protecting hnRNP F from ubiquitination and degradation...

The pro-tumoral effects of CCL5 have been identified in numerous cancer types. We successfully cultivated 4 esophageal squamous cell carcinoma (ESCC) cell lines, including TWES-1, TWES-3 and a pair of cell lines derived from primary lesion (TWES-4PT) and metastatic lymph node (TWES-4LN) of the same patient. Whole genome screening showed that TWES-4LN expressed higher levels of CCL5 compared to that of TWES-4PT; quantification of protein secretion displayed comparable results, suggesting that CCL5 could be associated with lymph node metastasis in ESCC...

Triple‑negative breast cancer (TNBC) is a highly aggressive breast cancer subtype that lacks effective targeted therapies. In the present study, we revealed that the expression of miR‑30a was significantly decreased in TNBC, and TNBC patients with low expression of miR‑30a were associated with high histological grade and more lymph node metastasis. Moreover, we found that miR‑30a suppressed TNBC cell epithelial‑mesenchymal transition (EMT), as demonstrated by the overexpression of miR‑30a which increased the expression of epithelial marker E‑cadherin but decreased the expression of mesenchymal markers N‑cadherin and vimentin...
